LaserMark-G is a versatile laser marking additive that enables stable, neutral gray contrast markings on engineering plastics. It is designed for applications where neither dark-on-light nor light-on-dark marking is optimal, delivering consistent readability across mixed-color or medium-absorption substrates.
| Parameter | W | SF | P | G | E |
|---|---|---|---|---|---|
| Primary Marking Objective | High dark contrast on light polymers | Sb-free dark marking | Reliable marking under difficult conditions | Colored / green marking | Stable marking in electronic & hybrid systems |
| Laser Interaction Type | Localized surface darkening | Localized surface modification | High-efficiency energy absorption | Color-selective laser response | Laser response stabilization |
| Resulting Mark Appearance | Black / dark gray | Black / gray | Dark, industrial contrast | Green or colored mark | Neutral contrast, controlled |
| Electrical Behavior Impact | Low impact in standard polymers | Electrically neutral | Low impact (not ESD-targeted) | Electrically neutral | Electrically neutral (insulating) |
| Cleanliness / Outgassing | Standard polymer grade | Standard polymer grade | Industrial grade | Standard polymer grade | Low outgassing / electronics-friendly |
| Best-Fit Application Class | Consumer goods, medical devices | Regulated consumer & industrial parts | Industrial, thick or filled parts | Visual coding, differentiation, branding | Connectors, sensors, ESD-sensitive parts |
| Processing Robustness | Broad processing window | Broad processing window | Very robust, wide laser window | Moderate, color tuning required | Stable, resin-dependent |
| When NOT to Use | ESD-critical electronic parts | When Sb is allowed and max contrast is needed | Aesthetic or decorative marking | When only black contrast is required | Simple cosmetic marking |
LaserMark-G is a laser-responsive functional additive designed to generate neutral gray contrast markings on engineering plastics.
2. How does LaserMark-G differ from LaserMark-W and LaserMark-SF?LaserMark-G provides balanced, gray contrast marking suitable for a wide range of substrates, while LaserMark-W focuses on dark marking on light plastics and LaserMark-SF enables light or foamed marking on dark plastics.
3. When should LaserMark-G be selected?LaserMark-G is ideal when substrate color varies, contrast requirements are moderate, or neither extreme dark nor light marking is desired.
4. Which laser systems are compatible?LaserMark-G performs effectively under common fiber (1064 nm) and green (532 nm) laser systems.
5. Is LaserMark-G a pigment or colorant?No. LaserMark-G is a functional laser-activation additive and does not act as a color pigment or filler.
6. Will LaserMark-G affect polymer properties?At optimized addition levels, LaserMark-G preserves the mechanical and surface properties of the base polymer.
7. Can LaserMark-G be combined with other functional additives?Yes. LaserMark-G can be used alongside stabilizers, fillers, or conductive additives with appropriate formulation balance.
